What are the causes of tailing in chromatography?
Tailing in chromatography can be caused by factors such as non-specific interactions between the analyte and the stationary phase, column overload, sample matrix effects, or inaccuracies in the injection process. These factors can lead to peak distortion, decreased resolution, and decreased sensitivity in chromatographic separations.
What is the effect if the paper is allowed to remain in the chamber after the solvent front has reached the top of the plate in a chromatographic work?
If the paper is allowed to remain in the chamber after the solvent front has reached the top of the plate in chromatographic work, it can lead to tailing or bleeding of the spots, causing them to spread and overlap. This can result in poor resolution and difficulty in accurately identifying and quantifying the separated compounds. Additionally, prolonged exposure to the solvent can alter the compounds being analyzed, potentially affecting the results. Therefore, it is crucial to remove the paper promptly to ensure clear and distinct separations.
Why ordinary liquid pump cannot be used in hplc system?
An ordinary liquid pump cannot be used in HPLC systems because HPLC requires pumps that can generate high pressure to push solvents through the column at a constant and precise flow rate. Ordinary pumps do not provide the level of pressure and flow rate control needed for HPLC separations, which can negatively impact the accuracy and reproducibility of chromatographic results. HPLC pumps are specifically designed to handle the high pressures and flow rates required for efficient separations.
How do you calculate Bandwidth W in chromatography?
Bandwidth in chromatography is typically calculated as the peak width at 5% of the peak height. This is done by measuring the width of the peak on the chromatogram at this 5% height point and can be used to assess the resolution and efficiency of the chromatographic separation. It is important in determining the quality and effectiveness of a chromatographic method.
What are the important parameters in brayton cycle?
The important parameters in Brayton cycle are the pressure ratio between the compressor and turbine, the efficiency of the compressor and turbine, the temperature of the gas at various points in the cycle, and the specific heat ratio of the working fluid. These parameters are crucial in determining the performance and efficiency of the Brayton cycle.
